Etiology and treatment of cancer-related secondary lymphedema.

Lymphedema and specifically cancer-related lymphedema is not the main focus for both patients and physicians dealing with cancer. Its etiology is an unfortunate complication of cancer treatment. Although lymphedema treatments have gained an appreciable consensus, many practitioners have developed and prefer their own specific protocols and this is especially true for conventional (manual) versus surgical treatments. This collection of presentations explores the incidence and genetics of cancer-related lymphedema, early detection and monitoring techniques, both conventional and operative treatment options, and the importance and role of exercise for patients with cancer-related lymphedema. These assembled presentations provide valuable insights into the challenges and opportunities presented by cancer-related lymphedema including the latest research, treatments, and exercises available to improve patient outcomes and quality of life.

Histologic Comparison of the Fascicular Area of Processed Nerve Allograft Versus Cabled Sural Nerve Autograft.

Background: The use of multiple cables of sural nerve autograft is common for peripheral nerve reconstruction when injured nerve caliber exceeds the nerve graft caliber. Although the optimal matching of neural to nonneural elements and its association with functional outcomes are unknown, it is reasonable to consider maximizing the neural tissue structure available for nerve regeneration. No prior studies have compared directly the cross-sectional fascicular area between cabled nerve autografts and size-selected nerve allografts. This study evaluated the cross-sectional fascicular area between native nerve stumps and two reconstructive nerve grafting methods: cabled sural nerve autograft (CSNA) and processed nerve allograft (PNA). Methods: CSNA from matched cadaveric specimens and PNA were used to reconstruct nerve defects in the median and ulnar nerves of six pairs of cadaveric specimens. Nerve reconstructions were done by fellowship-trained hand surgeons. The total nerve area, fascicular area, and nonfascicular area were measured histologically. Results: The CSNA grafts had significantly less fascicular area than PNA and caliber-matched native nerve. The PNA grafts had a significantly higher percent fascicular area compared with the intercalary CNSA graft. Conclusions: Fascicular area was significantly greater in PNA versus CSNA. The PNA consistently demonstrated a match in fascicular area closer to the native nerve stumps than CSNA, where CSNA had significantly smaller fascicular area compared with native nerve stumps.

Approach to Lymphedema Management.

Millions of people worldwide suffer from lymphedema. In developed nations, lymphedema most commonly stems secondarily from oncologic treatment, but may also result from trauma. More recently, lymphedema has been identified in patients after gender-affirmation phalloplasty reconstruction. Regardless of the etiology, the underlying pathophysiology involves blockage of lymphatic flow, resulting in lymph stasis, thus triggering a cascade of inflammation culminating in fibrosis and adipose deposition. Recent technical advances led to the refinement of physiologic and reductive surgeries-including lymphovenous anastomosis and free functional lymphatic transfer, which collectively encompass a variety of flap procedures including lymph node transfer, lymph channel transfer, and lymphatic system transfer. This article provides a summary of our approach in the assessment and management of the lymphedema patient, including detailed intraoperative photography and imaging, in addition to advanced technical considerations in physiologic reconstruction.

Transgender Scrotoplasty and Perineal Reconstruction With Labia Majora Flaps: Technique and Outcomes From 147 Consecutive Cases.

PURPOSE: Labia majora, the embryologic homologs of the scrotum, are ideal donor tissue for transgender scrotoplasty. The technique is detailed, and surgical outcomes are assessed for scrotoplasty using labia majora rotational advancement flaps. METHODS: We retrospectively reviewed the outcomes of phalloplasty patients who underwent either primary or secondary labia majora flap scrotoplasty and perineal reconstruction from October 1, 2017, to December 1, 2019. Bilateral elevation and rotational flap advancement from the posterior to anterior position formed a pouch-like scrotum. Perineal reconstruction involved multilayered closure with apposition of the inner thigh skin. RESULTS: The mean follow-up was 12.5 months (0.5-26 months). One hundred forty-seven scrotoplasties were performed. Of the 147 total scrotoplasty patients, 133 had labia majora flap scrotoplasty and perineal reconstruction with single-stage phalloplasty. Distal flap necrosis occurred in 6 patients (4.1%); 5 were ipsilateral to the groin dissection required for phalloplasty. Large (>1 cm diameter) perineoscrotal junction dehiscence occurred in 7 patients (4.7%). All wounds were managed conservatively except for 3 patients who developed urethrocutaneous fistulas at the perineoscrotal junction. All 3 patients required fistula repair. Two (1.4%) scrotal hematomas and 3 (2.0%) perineal hematomas were seen; all required operative intervention. CONCLUSIONS: Labia majora flap scrotoplasty via the bilateral rotational advancement technique and perineal reconstruction can be safely performed during phalloplasty. Minor wound complications are common and frequently heal with conservative management. Wounds that do not heal may be associated with urethral complications. Hematomas are rare but usually require operative intervention.

Bilaminate Synthetic Dermal Matrix versus Free Fascial Flaps: A Cost-Effectiveness Analysis for Full-Thickness Hand Reconstruction.

BACKGROUND: Full-thickness injuries to the hand require durable soft tissue coverage to preserve tendon gliding and hand motion. We aim to investigate the cost effectiveness of hand resurfacing comparing free fascial flap reconstruction versus bilaminate synthetic dermal matrices. METHODS: Cost effectiveness was modeled using decision tree analysis with the rollback method. Total active range of motion was modeled as the common outcome variable based on systematic literature review. Costing was performed from a payer perspective using national Medicare reimbursements. The willingness to pay threshold was determined by average worker's compensation for hand disability. Probabilistic sensitivity analysis was conducted for range of motion outcomes and the costs using 10,000 Monte Carlo simulations. RESULTS: The average cost of free fascial flap reconstruction was $14,201.24 compared with $13,674.20 for Integra, yielding an incremental cost difference of $527.04. Incremental range of motion improvement was 18.0 degrees with free fascial flaps, yielding an incremental cost effectiveness ratio of $29.30/degree of motion. Assuming willingness to pay thresholds of $557.00/degree of motion, free-fascial flaps were highly cost effective. On probabilistic sensitivity analysis, free fascial flaps were dominant in 25.5% of simulations and cost effective in 32.1% of simulations. Thus, microsurgical reconstruction was the economically sound technique in 57.5% of scenarios. CONCLUSION: Free fascial flap reconstruction of complex hand wounds was marginally more expensive than synthetic dermal matrix and yielded incrementally better outcomes. Both dermal matrix and microsurgical techniques were cost effective in the base case and in sensitivity analysis. In choosing between dermal matrix and microsurgical reconstruction of complex hand wounds, neither technique has a clear economic advantage.

An abnormal clinical Allen's Test is not a contraindication for free radial forearm flap.

An abnormal clinical Allen's test is not a definitive exclusion criterion for free radial forearm flap use. A surgical Allen's test may be useful to determine whether flap harvest is feasible in patients with an abnormal clinical Allen's test.

Radial Artery Occlusion in a Patient With Lupus, Antiphospholipid Syndrome, and Raynaud Phenomenon: A Multimodal Approach.

Radial artery occlusion (RAO) is a known complication of transradial catheterization for cardiac procedures. The transradial approach has decreased bleeding complications compared with the transfemoral approach, but risks provoking hand ischemia. We present a case of a 29-year-old peripartum woman with a history of lupus, antiphospholipid syndrome, and Raynaud phenomenon who developed RAO with hand-threatening ischemia despite therapeutic anticoagulation. Given the patient's medical history, a multimodal approach was applied including thrombectomy, arterial bypass, venous arterialization, and onobotulinum toxin A sympathectomy. The patient's ischemia improved after the procedure, and she regained normal use of the hand.
